CVE-2026-57128: Mervinpraison Praisonai

Medium severity, CVSS 4.3. EPSS: 0.3% chance of exploitation in the next 30 days.

PraisonAI is a multi-agent teams system. Prior to praisonaiagents 1.6.58, the SSE server in src/praisonai-agents/praisonaiagents/server/server.py does not consult ServerConfig.auth_token before handling /publish, /events, or /info requests. A network client that can reach the server can broadcast arbitrary events to connected clients and obtain server configuration and client-count information. This issue is fixed in praisonaiagents 1.6.58.

Affected products

• Mervinpraison Praisonai: before 1.6.58 (fixed in 1.6.58)
